B14 Series Motor Controller
Dual-motor independent vector control — one controller drives two motors
Overview
The B14 Series is a dual-motor non-isolated sinusoidal motor controller built on our proprietary FOC algorithm. It supports independent vector control of two motors — a single controller drives two motors simultaneously, for a more compact structure and lower cost. It delivers up to 97% efficiency with energy regenerative control extending vehicle driving range, in an IP66-rated housing.
- Dual-motor independent vector control (FOC / MTPA / SVPWM / Flux Weakening)
- Wide input voltage range 36–88 V
- IP66 protection rating
- Energy regenerative control extends driving range
- CAN 2.0 / 1-Wire communication
- High-power MOSFETs, forced air cooling
